If x y y2 shy x2 x y x y2 x y 2xy then value of 13 5 6 15 is ........

Logical Reasoning (CPO) Coding & Decoding

If x % y = y²  - x², x $ y = x + y², x # y = 2xy, then value of ((13 % 5) $ 6) # 15 is

480

720

- 360

-3240

Given:
x % y = y ² – x ² , x $ y = x + y ² , x # y = 2xy
((13 % 5) $ 6) # 15 = ?

After replacing the coded signs, the new equation will be as follows –
(13 % 5) = ((5)² – (13)² ) = 25 - 169 =-144

(13 % 5) $ 6 = (–144) + (6) ²= –144 + 36 = –108

(13 % 5) $ 6) # 15 = (–108 # 15) = 2 × (–108) × 15 = –3240

So, –3240 is the required answer.
